When it comes to motorcycles, the allure of power and speed is hard to resist. We’re often drawn to spec sheets boasting big horsepower figures, enormous engines, and top speeds pushing the limits of…
Niels MeersschaertHostYet we often peruse the spec sheets of the newest bikes and ogle at the horsepower and torque figures, or even just the displacement.
And while these quantifiable numbers make it easy to compare one motorcycle to another, they tell only a portion of the story.
This is usually one of the first things that people will use to describe a motorcycle.
They'll say, oh, how big is your bike? And they're referring not to the size of the bike's physical exterior dimensions most of the time.
So you might respond and say, oh, I've got a 1800cc or I've got a 900cc or even a 300cc bike.
In general, a larger displacement bike has more power than a smaller displacement bike.
The larger the displacement, the more power and torque that the engine is capable of producing.
And the very largest displacement motors that we have on the market today tend to be in large size cruisers.
Now, most large cruisers today are usually around that 1800 to 1900 cc range in terms of the overall size.
A lot of American cruisers, for example, would put this into cubic inches and it might be 119, 117 cubic inches larger.
So I'm going to stick with liters and CCs, which are just, you know, you can think of 1800 CCs as 1.8 liters.
It's a lot easier just mathematically to figure out than the cubic inches.
But of course, the largest displacement engine on the market today is the Triumph Rocket 3, which is 2,500 cc's.
